The UART on the RS9110-N-11-22 module is the physical interface which
transmits/receives the data from the Host. It supports variable baud rates
from 9600 to 3686400 bps. There is support for AT commands to configure
and operate the module through UART interface. Flow control is not
supported.
The HAL abstracts the lower layers in the host interface with which the
RS9110-N-11-22 module is connected. The HAL interacts with the Wireless
Control Block layer for the processing of the frames obtained from or destined
to the Host.
The data from/to the Host is classified as Wi-Fi specific frames and TCP/IP
specific frames. The WCB layer processes the frame obtained and acts
accordingly. The functionality of the WCB module depends on the type of the
frame and the direction of the frame (in case of TCP/IP) as described below.
The WCB interprets the Wi-Fi control information from the Host and interacts
with the SME (Station Management Entity).
If the frames from the host are interpreted as TCP/IP specific frames then the
WCB interacts with the TCP/IP stack.
The SME is the core layer which manages the Wi-Fi connectivity. The SME
maintains the state machine to detect the activity on the Wi-Fi network and
indicates to the user accordingly. It also performs re-association to the
configured access point in Infrastructure mode. It interacts with the WPA
supplicant if Security is enabled in the Wi-Fi network.
The WPA supplicant is used to initiate the 802.1x/EAP authentication if
WPA/WPA2-PSK is used as the security parameter. It also plays a major part
in performing the 4-way handshake to derive the PTK in WPA/WPA2-PSK
modes.
The RS9110-N-11-2X module supports three power modes. The Host can
switch among the power modes depending on the Wi-Fi connection status as
defined in this section.
In this mode, power save is disabled in the RS9110-N-11-2X module. The
module will be in Power Mode 0 by default.
